PAD. Wikipedia: Portable Application Description is a machine-readable document format designed by the Association of Shareware Professionals. It allows software authors to provide product descriptions and specifications to online sources in a standard way, using a simple XML schema that allows webmasters and program librarians to automate program listings. PAD saves time for both authors and webmasters. PAD files most commonly have .XML or .PAD file name extension.

- With generative art, the generative beings implemented can permanently create art expressions without ever repeating the same images or sounds, due to the richess of their inputs and of the random part of their algorithms.

It is centred around a supported programme of visiting fellows – artists, technologists, film-makers, theorists, post-media operators – and the production of a series of associated, international public events and publishing projects." - A web gallery.

Postmodern, postmodernism
The term is used notably for architecture, since the 1970's. Painting and music made this mutation sensibly earlier.
A major feature of postmodernism is the end of "great narrations". Everybody build their own specific narration. See for example the "database" philosophy of Azuma.
- [Dixon 2007]writes: "Our mistrust of postmodern critical perspectives derives partly from the fact that postmodern theory since the 1970's has largely perceived the ubiquity of media and the mediatized "image" as a cynical spiral of social domination and cultural degeneration. For many commentators, the coming of the difital age simply extends the paradigm. But, by contrast with others, including what we believe to be majority of the ditigal artists and performers we discuss, it has borne a new opimism about the potential of media... ".

Psychology. See major concepts, behavior, emotion.
- Psychology in digital art emerges at Laval Virtual 2014. See our post. Until then, it is surprising, if not shocking, that art and artists never pay attention to psychology (or sociology?). This topic is nearly considered indecent, pertaining to the realm of commercials. There are some exceptions. Ircam, for instance lists it as one of its research disciplines. But there is a substantial article in Wikipedia, with 68 (on 5/7/2013) references to primary - See emotion, expression, aesthetics, synesthesia.
Just to give ideas, some farfetched references:
- [Thibault 2010], in spite of its title La géométrie des émotions, is essentially formalist.

< Education through Art. by Herbert Read. Faber & Faber, London 1958.
- Uses of psychology in digital art, which could be enhanced by good theories and practical documents.
. artists could use it to build their projects, implement them, organize interaction.
. critics could evaluate the psychological effects on spectators.
. spectators, using comments by critics, could understand better and enjoy art.
- About digital art, two issues can be dissociated: psychology of art, psychology of the digital.
- Possible research tracks:
. typology/profiling of artists and their works
. "genetic" aspects of psychology, its development, from childhood to maturity and senescence; that is partly done in biographies.
- An example in [Read, see above], which evokes the digital aspect of art:: "It is usually assumed that a profound change occurs in the average child at about the age of 11, which change involves the desuetude of aesthetic modes of expfessino. Admittedly a profound change of a psychological nature does take place at this age. From our point of view it may perhaps be described ad the discovery of logical thought - the mental revolution so vividly described by Bergson, Claparède and Piaget. The child acquires the power of breaking up, or dissociating, his first unitary perceptions, and logical thought begins with this capacity to isolate and compare components details. From this comparative or correlating activity (Spearman's 'education of relation') proceeds the abstract thought of concept, and it must undoubtedly be true that the change thus introduced into the mental process of the child has a profound effect on his modes of expression. " (He continues with an accusation of society as destructive of creativity).
